Maths skills 1 (AQA GCSE Design and Technology): Flashcards

2D space a flat shape covers, in square units (m², cm²)

3D space inside a solid object, in cubic units (m³, cm³)

Total area of all outside faces of a 3D shape

A = l × w (length times width)

A = ½ × base × height (using perpendicular height)

A = πr² (π times radius squared)

V = a³ (edge length cubed)

V = (4/3)πr³

2πr² + 2πrh (two circular ends + curved side)

V = πr²h
